Perhaps you should try some spelling variations:
multiobjective optimized » multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
modified invasive » modified passive

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified invasive optimisation algorithm ) or ( modified multiobjective optimized algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified invasive optimisation algorithm ) OR ( modified multiobjective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified invasive optimisation algorithm ) or ( modified multiobjective optimized algorithms ))*.
